I had read about the amazing immediate results of using this Lypo-Spheric Vit C. Well I feel no different at all. I have a super bug in my lung and need to build up my immunity and someone recommended this product. My pharmacist warned me that it was not FDA approved so it has not been through a trial or test with the authorities. I feel I have wasted my money and regret spending over $60.00 plus postage.
